Lay oli' the width ol? the sheet of foraininousmaterial in two sections. Seo tion one oit this width should be as wideas the height of the interior cage B plus about one inch; section two ofthis width should be as wide as the height of the exterior cage il plusabout one inch.

Gather centrally the free top edge oi' the inner torna for the topol the interior cage B into approximately equal folds preferably four inninnber with loop ends 24, 5, 26, (Fig. of said folds extendingentwarf-ily and the sides 26, (Fig. 3) ot said loops extending centrallyleaving the openings l, and l, and l, la, :in -he tops 2li, (Fig. 3) otthe loops or folds. rl`he loops 24C, 5, 26, (Fig. 3) may extendcentrally gathered about a central object, il so desired, leaving any orall of the exits l, l", or l, or la in the tops oli the Yfolds loi'exits. lt the connnon base ol' the said two forms and adjacent to theline of fold en which section one ol the sheets oi loraininous materialwas folded over on section two centrally and simultaneously bend andcrinip an approximately equal partof each of said 'liornis about `oneinch wide or as wide as intended and laid out-iter lla-nge 2 (Fig. l) totorni said flange. Any sequence in which these operations inay beperformed in the method of torining cage B, cage A and flange 2, (Fig.l) is my inven tion though not described herein as to claim all thecombinations ot sequences el. said operations would be to submit amultitude of elaiins which it would seem the law does not contemplate ina claim for a inet-hed of forniing. Flange 2 with the recess above saidflange, llange 3 with the recess below said flange, and the annularyopening 1G betwee` flange 2 and flange 3 constitute a trap which devicetraps the fly immediately upon the entrance of the tl y into the tlytrap and said trap Vat the entrance ofthe nia-in trap may be referred toas an entrance trap. The inseetin cidal gerinicidal liquid i3, and ll,and used to lnoisten the wick 8 iu the cell il?, is pr A jrably thecorninon kerosene olI conunerce. rlfhe introduction oit an insecticidalgerini ci dal liquid in a chainber voi a l'ly trap to hasten the deathol 'dies within said trap or to cause the death ol" llies wil'l'iin saidtrap or :lor both of said purposes is a new invention when the death orthe haetening olf the death ol the flics er both elllects are caused bythe Contact el the liies with said liquid and is my invention.

ln using the trap, the parts are assembled hereinbeiiiore described andthe l placed in the bait chaiuberl) which is enough to hold a goodlyipiantity et Since the space for bait is ample, the ai be ot severalkinds each kind beh v placed in a separate receptacle a plan that hasinany advantages. The air circulates naturally through the ventilatorsi9 up through the bait protector Zl and on out through the trap. rllhellies 'ill he attracted to a. poi i outsifrle `lhe trap where the odorsilroui the ha are the strongest and this point will probably be at somepoint of the openi. g 1G in. the entrance trap. The trap being amplylighted andthe odors strongthe fliesare readily attracted through theopeningV 16 and are trapped immediately` by the entrance trap. Afterpassing through the entrance trap the flies settle on the sides of theinterior cage B or on the bait protector .4.- 1While seeking the baitthrough the bait protector l they soonflearn that they can not getthrough the bait protector to the bait and take wing to the sidesA andchannels of the interior cage B and at once start up the light and airychannels of the slightly inclined sides of B to the openings l .in thetops of the folds or crimps and pass into the exterior cage A. 'll heopenings l in the top of B and theshape' of the top of B constitute asecond trap which the flies have now passed and are hopelessly andsafely trapped. The fact that they did not have access to the bait keepsthem active and on the move from the first` entrance to the trap andthey naturally pass outward to the sides of the enteriorv cage A andupward seeking egress. rllhe frusto-conical top of A readily leads themtowards the chamber C and as they .rapidly grow restless and eager tofind egress they soonfind and pass through the passageways 23 intochamber C and are trapped within C by the trap 28. The flies are nowclosely confined and immediately seek the abundant light ofthe cell 27com.- ing through ythe transparent cap l0 and begin to fight against'the top and sides of l0 for egress settling soon on the wick 8 the onlyobject that offers a place of rest. Here their feet become moistenedwith the insecticidal germicidal liquid'of the wick and quickly take towing again tov fight the top and sides of 10 only to tire and settleagain on .the wick and become further moistened with` the insecticidalgermicidal liquid in saidwick and in this manner they repeatl theprocess described above soon to fall helplessly into the insecticidalgerinicidal liquid 15S-within the well 12 from which theyy never emergebut-'become submerged and are killed humanely where they remainharn'ilesseand where the germs on their bodies and feet and legs `aredestroyed in asanitary n'ianner. All of this usually happens iii-lesstime than it takes to tell it here. The-.humane :findfsanitary workingsofthe trap are of a highm'der. The {further fact that the flies do notcome in Vcontact with bait prevents their contaminating the bait withthe germs on their bodies and prevents their depositing their eggs tohatch in the bait.

A large number of dead flies may be conlined within a narrow space inthe welll-l. Said well may be cleaned outby removing the cap l() dippingthe flies out through the top of the well l2 and through 28 and 27 witha strainer dipper leaving the insecticidal germicidal liquid in the wellfor continued use. Said liquid being the common kerosene of commercedoes` not evaporate rapidly and said well l2 and the reservoir 9,k 7lado not need to be replenishedbut a few timeseach season. The bait may beplaced in the bait chamber D by removing the' flange which may be liftedfrom the top of the bait chamber and with said flange the superstructureabove said flange in a convenient way. The upper part of the trapcontinues to operate and kill the flies even while this process ofbaiting.- the trap is going on which baiting takes` but a few moments.Rain does not at'- fect the trap as it is constructed to shed the rain.The bait is secure from chickens, dogs, rats etc. The trap catches andkills all-flies that pass through opening and thus has a high degree ofelliciency. It is made of a high grade of material and isdurable and notrepulsive to operate and for these andlother reasons has `a tendency toencourage its use and create an interest in eradicating the fly. lll/lytrap is new and the method of making my trap is new.
